1. A taxon that includes a common ancestor, all descendants of that ancestor, and no other organisms is considered to be A) paraphyletic. B) polyphyletic. C) synapomorphous. D) monogamous. E) monophyletic. 2. The binomial system of nomenclature, by which we still classify species, was originated by A) B) C) D) E) Charles Darwin. Thomas Malthus. Carl Sagan. Ernst Mayr None of the above 3. Alloploidy A) can easily produce new plant species. B) occurs when a single plant duplicates its chromosomes. C) occurs when two plants of the same species breed D) occur when a tetraploid plant breeds with a diploid plant of the same species. E) results in plants that are usually outperformed by diploid relatives 4. The evolutionary relationship among organisms is known as A) taxonomy. B) phylogeny. C) paraphyly D) synapomorphy. E) homoplasy. 5. Any change in the DNA of an organism is termed a A) founder effect. B) mutation. C) speciation event. D) polymorphism. 6. The suffix "-idae" (e.g., Sciuridae) refers to organisms of what Kingdom? A) Bacteria B) Fungi C) Plant D) Animal E) ProtistExplanation / Answer
1) Paraphyletic : It is the group of organisms which includes the common ancestor and some but not at all of its descendants.
Polyphyletic:
The monophyletic group can be removed by single cut to a phylogenetic tree without the removal of any other species outside the group. so the taxon that includes a common ancestor all descendants of that ancdstor and no othe rorganisms is considered to be monophyletic.
Hence option (E) is correct.
2) The Binomeal nomenclature of by which we still classify the species was orignated by carlous linneaus.
so none of the above option.
Hence option (D) is correct.
3) Alloploidy : It occurs when two different species interbreed and produce a hybrid that is often sterile.
Eg. Evening primerose
4) The evolutionary relationship among organisms is known as phylogeny.
Hence option (B) is correct.
5) The any change in the DNA of organism is termed as a mutation.
6) The suffix of ideae refers to kingdom animal.
The suffix aceae fungi
